Double impatiens plant named ‘Cameo Light Pink’

ABSTRACT

A new and distinct cultivar of Double Impatiens plant named ‘Cameo Light Pink’, characterized by its extremely large soft pink-colored flowers; fully double flower form; freely flowering habit with flowers positioned above the foliage; compact, mounded, spreading, densely foliated, and freely branching plant habit; and large rounded dark green leaves.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Double Impatiens plant, botanically known as Impatiens walleriana, and hereinafter referred to by the cultivar name Cameo Light Pink.

The new Impatiens is a product of a planned breeding program conducted by the Inventor in Cartago, Costa Rica. The objective of the breeding program was to develop new compact Double Impatiens cultivars with large fully double flowers, excellent branching, and interesting flower and foliage colors.

The new Impatiens originated from a cross made by the Inventor of the Impatiens walleriana cultivar Confection Orange, not patented, as the male, or pollen parent, with the Impatiens walleriana cultivar Blitz Violet, not patented, as the female, or seed parent. The cultivar Cameo Light Pink was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Cartago, Costa Rica.

Plants of the new Impatiens differ from plants of the male parent, the cultivar Confection Orange, in the following characteristics:

1. Plants of the new Impatiens have fully double pink flowers whereas plants of the cultivar Confection Orange have semi-double orange flowers.

2. Flowers of plants of the new Impatiens are sterile whereas flowers of plants of the cultivar Confection Orange are fertile.

3. Plants of the new Impatiens are shorter than plants of the cultivar Confection Orange.

Plants of the female parent, Blitz Violet, and plants of the new Impatiens differ in the following characteristics:

1. Plants of the new Impatiens have fully double pink flowers whereas plants of the cultivar Blitz Violet have single purple flowers.

2. Flowers of plants of the new Impatiens are sterile whereas flowers of plants of the cultivar Blitz Violet are fertile.

3. Plants of the new Impatiens are shorter than plants of the cultivar Blitz Violet.

Asexual reproduction of the new cultivar by terminal cuttings taken at Cartago, Costa Rica, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Cameo Light Pink’. These characteristics in combination distinguish ‘Cameo Light Pink’ as a new and distinct cultivar:

1. Extremely large soft pink-colored flowers; freely flowering.

2. Fully double flower form.

3. Freely flowering habit.

4. Flowers positioned above the foliage.

5. Compact, mounded and spreading plant habit.

6. Freely branching habit.

7. Large rounded dark green leaves; densely foliated.

The new Impatiens can be compared to the Impatiens walleriana cultivar Pink Ruffle U.S. Plant Pat. No. 9,616. However, in side-by-side comparisons conducted in Lompoc, Calif., plants of the new Impatiens differ from plants of the cultivar Fiesta Pink Ruffles in the following characteristics:

1. Plants of the new Impatiens and plants of the cultivar Fiesta Pink Ruffles differ slightly in flower color, 65A and 62A, respectively.

2. Flower size is about 25% larger on plants of the new Impatiens compared to plants of the cultivar Fiesta Pink Ruffles.

3. Leaves of plants of the new Impatiens are larger, broader, more rounded and darker green than leaves of plants of the cultivar Fiesta Pink Ruffles.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new Impatiens. The photograph comprises a close-up view of typical flowers and leaves of ‘Cameo Light Pink’.

DETAILED BOTANICAL DESCRIPTION

The cultivar Cameo Light Pink has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The photographic illustrations and the following observations, measurements and comparisons describe about 6 week old plants grown in 10 cm pots in Lompoc, Calif., under commercial practice in a fiberglass-covered greenhouse with day temperatures about 21 to 24° C., night temperatures about 16 to 18° C. and light levels generally about 3,000 to 4,000 footcandles.

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
